Dive Brief: 

• Ad executive at media buying companies are accusing Google of pressuring them to utilize the search giant's ad buying manager DoubleClick Bid Manager in order to access its ad exchange. 
• Putting pressure for ad buyers to bundle could be considered a violation of the FTC's antitrust regulations because of Google's dominance as an ad exchange. 
• No formal investigation from the FTC has been confirmed, but according to a report from Digiday several ad executives have received contact from the FTC this year. 

Dive Insight: 

Encouraging customers to bundle items itself isn't illegal for any company—in fact it's quite common. Google is in a unique position, however, because it holds a near-monopoly on the ad exchange. A company in that position needs to be extra careful how they handle sales approaches because of the power they hold in the industry. 

A spokesperson from Google told Digiday she was not aware of any FTC inquiry happening.
